Packet Capture using EMX


#1

Does anyone know if it is possible to configure an EMX (or Chipworks) to promiscuously capture all network traffic being received on its network interface? I understand this will be limited by the processing bandwidth of the EMX.

thanks
Brian


#2

You need raw traffic and do not care for TCP/IP stack? Then maybe hook into the mac layer using RLP to read all incoming traffic.


#3

yes I would need RAW traffic.

I was hoping it could be done without RLP.
I guess I will be rethinking the requirements of this device or will be spending some quality time with the CPU and low level code.


#4

Another very easy option…connect ENC28J60 over SPI and read raw packets. You can actually connect multiple and then monitor multi-channels :slight_smile:

If there is a will, there is a way :slight_smile:

thank you
that looks like it should work and having multiple channels is a plus.

thanks again
